Brief Summary
Normal-hearing participants aged 18-25 with and without musical training will listen to a series of short musical samples that have been recorded through hearing aids. The music will be played at a comfortable listening level. Subjects will use the computer to rate the sound quality of the music on a 7-point Likert scale.

Study Arms (1)
Hearing Aid Signal Processing
EXPERIMENTALEach subject will listen to recordings of music processed by seven different hearing aid brands set to the default "Speech in Quiet" program and the default "Music" program. Recordings (hearing aid brand x program x music sample) will be randomized from trial to trial.
